Hi Dina
I have done a couple of charity events, one where I baked 700 cupcakes and one where I baked 500 cookies (thankfully not for the same event!) I did both of these from home as we are allowed to bake in our home oven for one off charity events here in New Zealand. The cupcakes took me a solid two days of baking and icing (just swirls of buttercream, no other decorations) and the same time frame with the cookies – they were iced with plain white fondant as they were for my sons school fair and the kids were going to handpaint them themselves! Both times I had an ‘employee’ (friend or family member) to help. So I would suggest that if you have someone who could help you? Even just to mix batter while you deorate – it’s very helpful, and moral boosting at the end of a long day :) If you are making sugar cookies, you could make up the dough and cut out the shapes 3-4 days in advance and leave them in the fridge until a couple of days before the event, then bake and decorate them two days in advance (they will still be fine) and then perhaps do the cupcakes the day before. As Jo said it will take 5-6 hours if you get a good rotation system going (and a helper) and if you make any flowers etc the week before or as in advance as you can this will cut time down too.
I didn’t make a cent off either of these big charity events, but I believe in karma and if you are going to be there serving these prominent ladies your creations (?) then the exposure for your business might be worth your time? Hope this helps a little bit and good luck! :)
